IMPROVEMENT m WATER-WHEELS.

Specification forming part of Letters Patent No. 174,750, dated March14, 1876; application filed January 15, 1876.

which throws out the bucket so as to take the water immediately afterpassingthe cut-off.

Figure 1 is partly a plan view and partly a horizontal section of thewheel; and Fig. 2 is a transverse section taken on line now of Fig. 1.

Similar letters of reference indicate correspondin g parts.

A is the periphery of the wheel, in which the buckets a are pivoted atB, so as to swing out to take the dead pressure of the water in passingalong the channelsO from the inlets D to the exhausts E, and to close infor passing the cut-off partitions F, which prevent back action of thewater.

G represents studs in the lower part of the wheel-case and within thewheel-rim, located so that an arm, H, of the buckets comes in contactwith them as soon as they have passed the partitions F, to swing themout for taking the water. They are closed by the partitions F, which arecurved at G, when the buckets strike suitably for making an easy action.

The water enters on the sides of the casing through the gates, of whichthere may be three or more, and is so conducted that it strikes thewheel in a tangential direction at the same time the water opens one ofthe movable buckets of the wheel, which now shuts up the whole openingthrough which the water has to pass, so that the water must spend itsfull force on the bucket.

While the wheel is in operation there are four buckets employed to eachgate. The first bucket is opened to receive the water; the second bucketcarries the water to the opening in the lower part of the casing, whereit is gradually discharged as the bucket moves on, thereby avoiding thejerk on the wheel which would otherwise occur if the sudden forcibleturning of the first bucket would not be resisted by the water betweenthe first and second bucket gradually discharging The third bucket movesright over the opening in the lower part of the casing, allowing thefull discharge of the water. The fourth bucket strikes the partitionwhich extends on one side of each gate toward, and close to, theperiphery of the wheel, and in so striking the bucket is closely shut tothewheel. These partitions must closely fit to the wheel, and the wheelmust be so tightly and accurately fitted to the casing as to prevent, asmuch as possible, the waste of water and any pressure of the water in acontrary direction.

The above described wheel combines the following merits and advantagesof a good water-wheel: a. It applies the Water-power in a tangentialdirection as the most efi'ective. b. It avoids any pressure of the Waterin a contrary direction. 0. It prevents in a high degree the waste ofwater. d. It works with any head of water; also under back water. e Theaction of the wheel can be adjusted to any given quantity or to anypower required by the partial or entire opening of the gates. f. Itemploys in the most effectual manner, the whole periphery of the wheelfor the utili zation of the water-power, thereby enabling it to realizethe same power by a smaller wheel as if only part of the periphery ofthe wheel would be employed. 9. It gives the advantage of the fullpressure of the solid column of water of a given head of water, withoutthe necessity of an accelerated motion, and consequently of an augmenteduse of water.

1am aware that it is not new to use springheld buckets closed againstcut-ofi's so as to produce a tangential impact of the water on wheel assoon as the bucket enters the chute; but what I claim is i A water-wheelwhose buckets are provided with inner arms H to strike studs G as soonas said buckets enter chutes G D, thereby opening one bucket to the fullstriking force of the water just as the preceding one enters the exhaustE, as and for the purpose specified.
